to store a date, you should probably use a date. to quote the documentation:

要存储日期，您可能应该使用日期。引用的文档:

The DATE type is used for values with a date part but no time part.

日期类型用于具有日期部分但没有时间部分的值。

You can store it as a DATE object as you would normally do with non-repeating dates. The, if you're using MySQL (I believe other DBMS also have functions for this) you can retrieve birthdays using MySQL functions as described here:

您可以将它存储为一个日期对象，就像您通常对非重复日期所做的那样。如果你正在使用MySQL(我相信其他的DBMS也有这个功能)，你可以使用这里描述的MySQL函数来检索生日:

SELECT * 
FROM table_name 
WHERE 
    MONTH(date_field) = desired_month AND 
    DAY(date_field) = desired_day

This method can be a bit slow when dealing with thousands of records. If that's your case, you can store the birthday with 3 separate INTs, one for each (year, month, day). Then you search birthdays like this:

当处理数千条记录时，这个方法可能有点慢。如果是这样的话，你可以用3个不同的INTs存储生日，每个INTs(年、月、日)一个INTs。然后你会这样搜索生日:

SELECT *
FROM table_name
WHERE
   month_field = desired_month AND
   day_field = desired_day

If you use this last method, I'd advise you to also store a DATETIME version of the birthday so that you can build the date without any kind of maneuvers. You can additionally index each one of the 3 fields (non-unique) so it's faster to retrieve them.

如果您使用最后一种方法，我建议您也存储一个日期时间版本的生日，以便您可以在没有任何操作的情况下构建日期。您可以为这3个字段中的每个字段(非唯一字段)添加索引，以便更快地检索它们。

"DATE" should be good.

“日期”应该不错。

The DATE type is used for values with a date part but no time part. MySQL retrieves and displays DATE values in 'YYYY-MM-DD' format. The supported range is '1000-01-01' to '9999-12-31'.

日期类型用于具有日期部分但没有时间部分的值。MySQL检索并显示“YYYY-MM-DD”格式的日期值。支持的范围是“1000-01-01”到“9999-12-31”。

You should store the date as DATE.

您应该将日期存储为日期。

And the Locale as a varchar (PHP or Java).

并且区域设置为varchar (PHP或Java)。

Don't forget the Locale :)

不要忘记语言环境:)

Nothing like getting an Email from something like Weibo (Chinese Twitter) when its not your birthday yet.

没有什么比收到微博(中国的推特)这样的邮件更让人兴奋的了。
